regarding how to keep you house cooler in the summertime by cooling the attic with a box fan.

I was wondering what you guys think of it?

Do you think it would work?

Do you think there is a fire danger with the heat/electricity in the attic?

Sure, it'll help ventilate and cool that house. Real bargain basement
way to do it, but it's a lot better than nothing.

I don't think much of it because I have A/C to cool my living space,
and the attic is cooled by a powered roof ventilator pulling outside
air in from soffit vents and exhausting it out the roof.
Attic is insulated too.
So they're separately ventilated spaces.

But if I had his situation and wanted to spend the least money
possible, I'd do something similar.
When I lived in house with no A/C I used box fans a lot to direct
outside air in the house.
One in the living room window, and one in the kitchen window, both
blowing air out. Then we'd get a "cool" breeze coming in the bedroom
window, and sleep pretty well on hot nights - with no fan noise.
That house was flat roof, no attic.

That guy basically put in what's usually called a "whole house" fan,
on the cheap. It nothing but win-win for him really.
All it has to do is knock a couple degrees off the living space and
attic temperatures. And it probably does.

As far as "fire danger" if he uses good cords there shouldn't be any.
That box fan uses very little current.
